Asiana Airlines Flight 214 crashed in San Francisco on July 6 .

The Boeing 777 operated by Asiana fell short of its approach and crashed on the runway at San Francisco International Airport . Three people were killed and more than 180 others hurt .

The lawsuit alleges that some equipment on the plane was improperly installed or defective , resulting in inadequate warnings for the pilots about low airspeed .

`` Boeing was aware that its low airspeed warning system was inadequate , '' the suit states .

More than 80 of the plane 's 291 passengers are named as plaintiffs in the lawsuit .

`` As a result of the crash , each of the plaintiffs sustained injuries , including but not limited to , bodily injury and resulting pain and suffering , disability , mental anguish , loss of capacity for the enjoyment of life , medical treatment , loss of income , and medical expenses , '' the suit states .

CNN reached out to Boeing for comment about the lawsuit . Company spokesman Doug Alder declined to comment .

The passengers represented by Ribbeck Law began their court proceedings shortly after the crash , filing a petition for Boeing to release evidence to the plaintiffs .

At the time , the law firm said it was considering adding Asiana and certain parts manufacturers to the lawsuit , but Friday 's filing named only Boeing , Kelly said .
